**Android通讯录模糊匹配搜索实现（号码、首字母、简拼、全拼）**

2013年12月10日   
工作记录

小巫在工作中碰到一个需求，要求实现通讯录联系人的搜索，获取联系人的方式有好几种，我都有点混乱了，下面提供我最近用的一种，看起来还算比较简洁的，它是根据mimetypes表来查的。

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain] [![在CODE上查看代码片][CODE]][CODE_CODE] [![派生到我的代码片][ico_fork.svg]][ico_fork.svg 1]

1.  // 查询所有联系人的姓名，电话，邮箱
2.  
3.  public ArrayList<Contact> loadContacts() throws Exception \{
4.  
5.  Uri uri = Uri.parse("content://com.android.contacts/contacts");
6.  
7.  ContentResolver resolver = this.getContentResolver();
8.  
9.  Cursor cursor = resolver.query(uri, new String\[\] \{ "\_id" \}, null, null,
10. null);
11. ArrayList<Contact> contacts = new ArrayList<Contact>();
12. while (cursor.moveToNext()) \{
13. 
14. Contact contact = new Contact();
15. int contractID = cursor.getInt(0);
16. 
17. StringBuilder sb = new StringBuilder("contractID=");
18. 
19. contact.setId(String.valueOf(contractID));
20. sb.append(contractID);
21. 
22. uri = Uri.parse("content://com.android.contacts/contacts/"
23. \+ contractID + "/data");
24. 
25. Cursor cursor1 = resolver.query(uri, new String\[\] \{ "mimetype",
26. "data1", "data2" \}, null, null, null);
27. 
28. while (cursor1.moveToNext()) \{
29. 
30. String data1 = cursor1.getString(cursor1
31. .getColumnIndex("data1"));
32. 
33. String mimeType = cursor1.getString(cursor1
34. .getColumnIndex("mimetype"));
35. 
36. if ("vnd.android.cursor.item/name".equals(mimeType)) \{ // 是姓名
37. contact.setName(data1);
38. sb.append(",name=" \+ data1);
39. 
40. \} else if ("vnd.android.cursor.item/email\_v2".equals(mimeType)) \{ // 邮箱
41. if (!TextUtils.isEmpty(data1)) \{
42. contact.setEmail(data1);
43. \}
44. contacts.add(contact);
45. sb.append(",email=" \+ data1);
46. 
47. \} else if ("vnd.android.cursor.item/phone\_v2".equals(mimeType)) \{ // 手机
48. contact.setNumber(data1.replaceAll("-", ""));
49. sb.append(",phone=" \+ data1);
50. \}
51. 
52. \}
53. contacts.add(contact);
54. cursor1.close();
55. 
56. Log.i("wwj", sb.toString());
57. 
58. \}
59. 
60. cursor.close();
61. return contacts;
62. 
63. \}

// 查询所有联系人的姓名，电话，邮箱
    
    	public ArrayList<Contact> loadContacts() throws Exception {
    
    		Uri uri = Uri.parse("content://com.android.contacts/contacts");
    
    		ContentResolver resolver = this.getContentResolver();
    
    		Cursor cursor = resolver.query(uri, new String[] { "_id" }, null, null,
    				null);
    		ArrayList<Contact> contacts = new ArrayList<Contact>();
    		while (cursor.moveToNext()) {
    
    			Contact contact = new Contact();
    			int contractID = cursor.getInt(0);
    
    			StringBuilder sb = new StringBuilder("contractID=");
    
    			contact.setId(String.valueOf(contractID));
    			sb.append(contractID);
    
    			uri = Uri.parse("content://com.android.contacts/contacts/"
    					+ contractID + "/data");
    
    			Cursor cursor1 = resolver.query(uri, new String[] { "mimetype",
    					"data1", "data2" }, null, null, null);
    
    			while (cursor1.moveToNext()) {
    
    				String data1 = cursor1.getString(cursor1
    						.getColumnIndex("data1"));
    
    				String mimeType = cursor1.getString(cursor1
    						.getColumnIndex("mimetype"));
    
    				if ("vnd.android.cursor.item/name".equals(mimeType)) { // 是姓名
    					contact.setName(data1);
    					sb.append(",name=" + data1);
    
    				} else if ("vnd.android.cursor.item/email_v2".equals(mimeType)) { // 邮箱
    					if (!TextUtils.isEmpty(data1)) {
    						contact.setEmail(data1);
    					}
    					contacts.add(contact);
    					sb.append(",email=" + data1);
    
    				} else if ("vnd.android.cursor.item/phone_v2".equals(mimeType)) { // 手机
    					contact.setNumber(data1.replaceAll("-", ""));
    					sb.append(",phone=" + data1);
    				}
    
    			}
    			contacts.add(contact);
    			cursor1.close();
    
    			Log.i("wwj", sb.toString());
    
    		}
    
    		cursor.close();
    		return contacts;
    
    	}

关于模糊匹配，我真的有点头大，我想到的是用正则表达式来做，但需要用到**第三方类库pinyin4j.ja**r，我试了一下，效率都点低，明显感觉有点慢了，假如你的通讯录的量比较大，用这个来做确实不合时宜，或许可以进行优化的地方。

上面的代码是我从网上搜了很久才搜到的一个demo里面的代码，我整合到项目当中去，发现使用pinyin4j.jar类库效率实在有点低，所以我自己想了其他办法，不用第三方类库来实现。

**下面是小巫的实现：**

不过我也发现了一问题，关于一个中文字符的字节数的问题，不同的编码可能会存在中文的字节数不同的情况，比如GBK编码的中文是2，而UTF-8的编码是3。其实我发现这个问题也挺惊奇的，这个问题可能是我们以后编码的时候会遇到的，一个编码就可能把你搞死。

[**英文字母和中文汉字在不同字符集编码下的字节数**][Link 1]

英文字母：

字节数 : 1;编码：GB2312

字节数 : 1;编码：GBK

字节数 : 1;编码：GB18030

字节数 : 1;编码：ISO-8859-1

字节数 : 1;编码：UTF-8

字节数 : 4;编码：UTF-16

字节数 : 2;编码：UTF-16BE

字节数 : 2;编码：UTF-16LE

中文汉字：

字节数 : 2;编码：GB2312

**字节数 : 2;编码：GBK**

字节数 : 2;编码：GB18030

我发现自己换了这种方法之后，速度一下子提升了很多，满足了自己的需求，用第三方类库虽好，但涉及到用户体验这一块，你不得不低头，小巫总结在此，这篇博客我相信总会有人需要的，如果有帮助到你，不要忘记好评哈，你的支持将是我无限的动力。
